OEM Carrier Fan Blower Control Board HK61EA002 for Model FB4ANF042010AFAA

This is the factory OEM fan blower control board (part number HK61EA002) for the Carrier FB4ANF042010AFAA air handler. The control board serves as the central command module for blower motor operation — managing fan speeds, delay timings, and communicating with the thermostat and system controls. When this board fails, you may experience symptoms such as the blower fan not running, the fan running continuously regardless of thermostat calls, intermittent or erratic fan behavior, fault code lockouts, or a complete loss of air handler function. Replacing this board with the correct OEM unit restores factory-programmed logic and ensures precise, reliable operation of your air handler system.

• Install difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage before handling. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring connections before removal.
